Searching and displaying data objects residing in data management systems

ABSTRACT

A data source is accessed to provide information. The data source is accessed by defining a plurality of data objects each associated with data within the data source, where the data objects include search information that facilitates searching of the data objects, and the data objects further include display information that pertains to a format in which data obtained from a search of the data objects is displayed, defining one or more relationships linking at least one data object with at least one other data object so as to establish associated data objects with linking relationships, receiving a query to search for data within the data source, retrieving data within the data source satisfying the query in accordance with the search information, where the retrieved data comprises data from at least two associated data objects, organizing and displaying the retrieved data in accordance with the display information, and displaying one or more links associated with the retrieved data so as to enable navigation between associated data objects.

BACKGROUND

1. Technical Field

The present invention relates to searching, displaying and navigating of data objects within data management systems.

2. Discussion of the Related Art

Searching data is known and primarily limited to unstructured data including web pages, email and documents. Traditional search engines such as Google search are used to search documents and pages for specific key strings. When a document or web page contains a particular string, it is returned as part of search results.

Many forms of valuable data are stored as structured data in data management systems, such as relational database management systems. In particular, relational database management systems include data stored in tables, where database records are ordered in rows of the tables. Database schemas are provided by the database management systems to describe the organization of data and information within the databases. For example, in relational database management systems, database schemas are provided to describe the organization of data and information in tables, columns and fields within tables, indexes for the tables as well as relationships between the tables, columns and indexes.

Some search engines are capable of searching relational database management systems. Such search engines typically treat each row of data obtained from the search as a complete search object and return the entire row in the search results. This requires the searcher to have to relate each row with the rest of the data in the database to obtain usable results from the search query.

DETAILED DESCRIPTION

In accordance with embodiments of the present invention, a method, system and computer program product are provided which facilitate searching and retrieval of single or multiple data sources or databases and obtaining results that are organized in a manner that is suitable for identification of relationships between data in the results. In particular, searching of single or multiple data sources or databases can be achieved utilizing previously defined data objects, where the data objects exist as a cluster of related tables in one or more database management systems. Instead of searching individual records and providing search results as flat, scattered fragments of records, the data in all tables in a data object is searched and the search results are configured as instances of data objects that are connected through hyperlinks. In other words, instances of data objects are displayed with links to associated instances of data objects so as to enable navigation between two or more associated data objects.

Any suitable system and method can be utilized to facilitate retrieval of data from one or more databases. Example embodiments of systems and corresponding methods for determining relationships and mappings between data in different databases and for facilitating retrieval of data from databases based upon a search query are described in U.S. Pat. Nos. 7,426,520 and 7,680,828, both of which are incorporated herein by reference in their entireties. However, it is noted that the present invention is not limited to these example embodiments but instead can utilize any suitable systems and methods that facilitate retrieval of relevant data from one or more data sources, where the features of the present invention provide for presentation of the data in a manner such that instances of data are linked with associated instances of data by hyperlinks (thus allowing for a quick and easy navigation of the data in the search result in order to provide more useful information to the user searching for the information from the one or more databases).

An example embodiment of a system for facilitating data retrieval from a plurality of databases or data sources is shown in FIG. 1. In particular, the system or enterprise 100 includes data management systems 102 a-c, data sources 104 a-c, and a data object search system 105 coupled with each of the data management systems. The data object search system 105 comprises a data mapper 106, a data object crawler 108 and a data object searcher 110. It is noted that the data mapper 106, data object crawler 108 and data object searcher 110 can be formed as a single component or, alternatively, as any two or more separate components defining the data object search system 105.

Data management systems 102 a-c and data sources 104 a-c are hereinafter referred to as data management systems 102 and data sources 104, respectively. System 100 can be any type of enterprise including, without limitation, a commercial enterprise, educational enterprise, or financial enterprise. Data management systems 102 can be any suitable types including, without limitation, accounting data management systems, Customer data management systems, Account data management systems, Employee data management systems, etc.

Data management systems 102 include data sources 104. For example, with reference to FIG. 1, data management system 102 a includes data source 104 a, data management system 102 b includes data source 104 b, and data management system 102 c includes data source 104 c. Data sources 104 may be operational data sources, data-warehouse data sources or federated data sources. An operational data source is used in an operational data management system. An operational data management system accepts queries from a user, identifies the information on the basis of the queries, and returns the results to the user. The operational data management system also accepts updates from the user, and accordingly, updates data in the operational data source. Examples of operational data management systems include, without limitation, On Line Transaction Processing (OLTP) data management systems, custom-billing data management systems, and Management Information Systems (MISs). A data-warehouse data source is a data repository, which integrates data from various data management systems. Examples of data-warehouse data sources include, without limitation, data marts and enterprise data warehouses. A federated data source is used to make multiple operational and/or data-warehouse data sources appear as a single integrated data source. It is to be understood that the specific designation of data sources 104 and data management systems 102 in FIG. 1 is for purposes of example, and the present invention is not limited to the specific design of the enterprise 100. For example, while the embodiment of FIG. 1 shows each data management system 102 with a single data source 104, it is noted that each data management system can include two or data sources.

Each data source 104 can include data in the same format or, alternatively, in a different or proprietary format. For example, data in data management system 102 a may be in Data Base 2 (DB2) format, while data in data management system 102 b may be in Oracle format. The data in the data management systems are integrated with each other in order to facilitate searching across two or more data management systems.

The process of integration and organization of data between the different data management systems is performed by the data mapper 106. The data mapper 106 determines the relation between data stored in one or more data sources 104 and then maps data. For example, the data mapper 106 is capable of mapping data from a source data management system to a target data management system. The data object search system 105, which includes the data mapper 106, is coupled in any suitable manner to each data management system 102 so as to facilitate access of data from each data management system by the data mapper 106. In addition, the data mapper 106 allows a user to select a plurality of data sources from data sources 104, and then map data sources 104 in any combination. For example, a user may select data source 104 a in data management system 102 a as the source data source and data sources 104 d and 104 e in target data management system 102 d as the target data sources.

Data in a data source can be stored in various data tables to form data objects. The data mapper 106 determines the relationships between the data tables in the data objects by identifying primary keys and foreign keys in the data tables. The data tables and their relationships may be illustrated in the form of relationship graphs. A primary key is a set of attributes that uniquely identifies an entity, which is a certain unit of data that can be classified and has stated relationships to other entities. For example, a data object providing information about customers can be generated including each customer as an entity, in which attributes of each customer include columns from one or more data tables with instances of data disposed in the columns. Each entity includes one or more instances of data from the data tables. The primary key is unique, stable, and non-zero under all conditions. A foreign key of an entity in a data table provides referential information about the entity. The foreign key provides the relation between the entity in the data table and entities in other data tables. Further, a foreign key of one of the data tables can be a primary key of another data table.

The data mapper 106 identifies the relationships between the data tables in a single data object or in two or more data objects on the basis of the identified primary and foreign keys. Data-table relationships can be classified into different types of relationships including, without limitation, an attribute relationship, a reference relationship, and a cross-reference relationship. An example of identification and mapping of relationships between the data tables by data mapper 106 is described in detail in U.S. Pat. Nos. 7,426,520 and 7,680,828.

In an attribute relationship, a parent table describes an entity, and a child table includes additional information about the entity. The parent table is a data table that links various child tables. The child tables and the parent table include at least one common column. The child tables will typically further include additional columns, in certain embodiments of the invention. In a reference relationship, a child table describes an entity, and the parent table includes reference information about the entity. In a cross-reference relationship between two entity tables, the two entity tables provide reference information about an entity. An entity table is a data table, wherein the primary key of the data table does not include any foreign key of other data tables.

The data mapper 106 identifies the data tables on the basis of the identified primary and foreign keys, and the identified relationships between the data tables.

Data tables in an operational data source can be classified into operational system tables, cross-reference tables, attribute tables, and entity tables. An operational system table is a data table that stores metadata of data tables of the operational data source. A cross-reference table is a data table, where the primary key of the data table includes foreign keys from other data tables. An attribute table is a data table, where a part of the primary key of the data table includes a foreign key of another data table.

Data tables in a data-warehouse data source can be classified into data-warehouse system tables, fact tables, dimension tables, reference tables, and attribute tables. A data-warehouse system table is a data table that stores metadata of data tables of the data-warehouse data source.

A federated data source includes multiple operational and/or data-warehouse data sources. Therefore, the federated data source may be either an operational data source or a data-warehouse data source.

The data mapper 106 generates a Local Data Object (LDO) on the basis of the identified data-table relationships and data-table types. The LDO provides a logical representation of the relationships between the data tables in the data source. However, it is noted that a data source can have multiple LDOs. It is also noted that an LDO can correspond to only some data tables in the data source instead of all the data tables. For example, a data source can have three data tables, Customers, Addresses, and Orders. However, an LDO of the data source, CustomerLDO, may correspond to only two of the data tables, Customers and Addresses, while another LDO, OrdersLDO, also corresponds to only two of the data tables, Customers and Orders. Therefore, CustomerLDO provides the logical representation of the relationships between data related to customers, while OrderLDO provides the logical representation of the relationships between data related to orders.

The LDO has a root table that includes the natural key of an entity in the LDO. The natural key is a subset of attributes of the entity, which uniquely identifies the entity. The root table does not have any parent table. All other tables represented in the LDO are child tables related to the root table. The LDO includes parent-child relationship expressions of the data tables. The parent-child relationship expressions may be based on the primary-foreign key relationships between the data tables, for example, in case of a Relational Database Management System (RDBMS).

The data mapper 106 generates LDOs for all data sources 104. One data source can have a single LDO or several LDOs. In addition, a particular data table can be represented in more than one LDO. Examples of LDOs are depicted in U.S. Pat. No. 7,680,828.

Data mapper 106 also generates a Global Data Object (GDO). The GDO is a data object that corresponds to an entity. The GDO is a data model that consolidates a plurality of LDOs into a single integrated model. The GDO includes the relationships between the plurality of LDOs. Therefore, the plurality of LDOs are mapped onto the GDO. Example embodiment of generating a GDO and LDOs that are mapped to a GDO are described in U.S. Pat. Nos. 7,426,520 and 7,680,828.

The GDOs facilitate data retrieval from data sources 104 of data management systems 102. When a search query is requested, the GDO corresponding to the data associated with the search query is referenced, and that GDO provides the information on how to retrieve the required data.

Thus, data objects from data sources of one or more data management systems are mapped together (e.g., by forming LDOs and GDOs as described above), and a search query by a user for results in data provided by the mapper, including entities that are related from two or more data sources. The data mapper 106 stores data objects and definitions (including LDOs, GDOs, primary and foreign keys and related information) within a repository 120 that is also accessible by the data object crawler 108 and data object searcher 110.

As noted above, search results from data management systems, in particular, relational database management systems, are typically provided by retrieving rows of data from data objects. While such search results are relevant, they are not in an organized manner that allows a user to easily navigate from one instance of data to another, related instance of data.

In an example embodiment of the invention, primary and foreign keys of the tables in the data objects retrieved from a search query are utilized to provide a linking between related instances of data that may be in different tables or different data objects. In particular, the retrieved data is displayed in a format that utilizes primary keys and foreign keys between tables to establish hyperlinks in the displayed data, and these hyperlinks facilitate easy navigation by the user between related instances of data in the search results.

The flowchart of FIG. 2 provides an example method of searching data objects in an enterprise comprising one or more data management systems such as the enterprise 100 of FIG. 1. In particular, data objects, which comprise data tables in one or more of the data sources of the enterprise, are initially defined or established (step 200). The data objects are defined and linked or mapped to each other, for example, using the data mapper 106 and the methods described above. As noted above, the data objects comprise tables of data from one or more data sources, and the primary keys and foreign keys associated with the data tables and data objects provide links between associated or related data objects and associated or related instances of data for one or more data objects. The data mapping also determines how queried information is to be displayed for associated data objects. As described below, the user can also specify which data object attributes are searched and which are to be displayed as part of search results. The data objects, primary and foreign keys and related definitions and information regarding the data objects is stored by the data mapper 106 in the repository 120.

After data objects have been defined, the data object crawler 108 browses or crawls the data objects and related information in the repository 120 in order to build a search index 130 (step 210). The search index 130 can be designed in any suitable manner to facilitate efficient processing of a search query by searching the search index to find data within the data objects that is related to the search query. For example, the search index 130 can be built in a similar manner in which a search engine (e.g., www.google.com) crawls the world wide web to generate a search index that is searched to obtain search results based upon a search query. The data object crawler 108 crawls the data objects and related information stored in the repository 120 to generate an index in which data objects are associated with values of the fields in the data object, such that a search on a search string will return the identities of the data object instances that contain values that match the search string. The identities may be expressed in any number of ways, including data object type and primary key value, special generated identifier assigned to each data object instance by the search crawler or any number of other ways. For example, if an instance of a Customer Data Object for a company Google has an attribute state that contains a value ‘California’, a search on ‘California’ in the search index will return the identity of Customer Data Object instance for Google. The data for the Data Object instance that the search index would point to would contain all the information required to display the fields in the Data Object as well as create the hyperlinks that relate this Data Object instance to other data objects via the primary and foreign keys associated with those data objects. This data may be stored as an XML document or some other file format, it can be stored in a relational database or can be retrieved at run time from the source systems. Many methods of caching and retrieving data exist and can be utilized. In an example method, only the data necessary to present search results is stored in the local index or cache and the rest of the data is retrieved at run-time from the source system. Alternatively, it is noted that the data object search system 105 can process a search query by searching the data objects and related information in the repository 120 directly instead of using a search index 130.

A search query from a user (the user is represented by box 140 in FIG. 1) is received and processed by the data object search system 105 (step 220). In particular, the data object searcher 110 of the data object search system 105 receives and processes the search query from the user 140, where the data object searcher 110 utilizes the search index 130 and repository 120 to identify and retrieve information comprising instances of data from one or more data objects that satisfy and are relevant to the search query (step 230). The retrieved information is organized and displayed in accordance with how information for associated data objects is to be displayed (step 240). In particular, the displayed information includes instances of data objects which are hyperlinked to other related instances of data objects. When a user navigates a particular hyperlink in the display associated with a first instance of data, the data object searcher 110 provides a further display of organized information including a second or further instance of data that is related (via primary or foreign key) to the previous or first instance of data (step 250).

Thus, each data object is searched by the data object searcher in response to a search query by a user, including all (or selected) tables and all (or selected) attributes making up each data object. When a suitable match between an instance of data in a table column of a data object and the search query is obtained, the search result does not simply return the row of the table including this matching instance of data but instead returns the matching instance of data as well as other instances of data from the data object that have been designated for display, including instances of data associated with other rows of the same data table and/or instances of data associated with other data tables of the data object.

Example scenarios showing how search queries of data objects from one or more data sources are displayed, including links between related instances of data, are now described.

Referring to FIG. 3, a graphical user interface is depicted showing a table of search results for a commercial enterprise in which customers, customer orders, reports and other instances of data are available for display to a user based upon a search query. The data from different data sources is organized by a data mapper 106 (e.g., in the manner described above) by defining data objects and linking a number of data objects and data instances together by primary and foreign keys. In this example, a user 140 performs a search utilizing the data object search system 105, where the user provides a search query for customer information having the term “popcorn” in the customer name. The data object search system 105 identifies, via the defined data objects, instances of data that are relevant to the search criteria and provides the data in the display shown in FIG. 3. In particular, the displayed search results are in a table including customers having the term “popcorn” in the customer name (as shown in the Company column 302), along with other information such as customer address (shown in Address, City and State columns 304), account manager for each customer (shown in Account_Manager column 306), orders and reports that can be provided for each customer. Defined data objects can be, for example, a Customer data object, Account Manager Data object, Orders data object, etc.

Certain columns of data provide hyperlinks to related data via primary and foreign keys of the data objects. For example, a hyperlink is provided to an Account Manager data object based upon primary-foreign key relationships between the Account Manager data object and the Customer data object. The window 310 shown in FIG. 3 shows an example of an instance of Account Manager data for the company Popcorn Videos that can be easily navigated via the hyperlink to Account Manager information from the displayed table of information, where the hyperlink is based upon primary-foreign key relationships between the Customer data object and the Account Manager data object. In addition, hyperlinks are provided in the Related Lists column 308 to allow the user to navigate to lists of orders associated with the particular customer via primary-foreign key relationships between the Customer data object and the Orders data object.

Other types of related information may be made available and associated with search results through parameterized calling strings (such as a HTTP string or a command line string) that pass information about a particular data object to the reporting system. For example, the Reports and Analytics column 309 can be configured to provide reports with selected types of information (e.g., end-of-month reports, end-of-quarter reports, and other types of sales analysis reports) by hyperlinking to a reporting system and passing necessary information (such as customer identifier) as part of the hyperlink. The reporting and analytics column associates a particular report (e.g., end-of-month report) with a particular attribute (e.g., customer name attribute) for a data object (e.g., Customers data object) by providing a hyperlink associated with that particular data object which will link with the report for that data object attribute.

In the example shown in FIG. 3, an end-of-month report could be hyperlinked to a particular customer utilizing a link such as “http://reports.myreportingsystem.com?custname=<customer name>”, where “<customer name>” is the name of the customer for the particular customer attribute associated with the report. The correct report can be associated with the corresponding attribute of the Customer data object by creating a template hyperlink “http://reports.myreportingsystem.com?custname=<$Company>” and associating it with Customer data object. When the search results are returned, the hyperlink will get filled in with the value of Company attribute for each returned instance of the data object. For example, the “EOM Report View” hyperlink would be set to http://reports.myreportingsystem.com?custname=Popcorn Videos 1 for the first row, to http://reports.myreportingstem.com?custname=Popcorn 2 for the second row, etc.

The displayed information shown in FIG. 3 can also include a window 312 that filters the search results based upon city and state, where a hyperlink for a specific city will show only the customers in that city. The graphical user interface of FIG. 3 also provides the feature of displaying the search results on multiple pages, with the option of navigating to a specific page of search results (as shown in the box 314).

The data can be organized and provided by the data object searcher 110 in any suitable manner, with any suitable number and types of hyperlinks to related data based upon primary-foreign key relationships between defined data objects, where the amount and types of data provided are based upon any number of factors including, without limitation, the search criteria, the number of relationships defined between instances of data and data objects, and the security level of the user (e.g., the user may have limited or restricted access to certain types of data) and/or types of data typically accessible by a user. A user can further design or customize the types of data for display, as described in further detail below.

In another example scenario that includes a graphical user interface as depicted in FIGS. 4-7, an investment banking enterprise includes a plurality of data management systems with data sources and a data object search system to map data and to and facilitate a search, navigation and display of search results, where the system is similar to that described above and depicted in FIG. 1. The data is defined in tables of a plurality of data objects stored in a plurality of data sources of the data management systems. As shown FIG. 4, the data objects include a plurality of data objects that have been defined by a data mapper of the data object search system, including a Customers data object 402, a Loans data object 404, and a Purchase Orders data object 406. The information shown in the display of FIG. 4 is the result of a search of the enterprise for a search string ‘ABCD’, which returns all information relating to ABCD Company. In particular, the instances of data in the search results for the Customers data object 402 comprise different office/branch/division locations for ABCD Company, with corresponding address information, contact information, the account manager associated with the particular office location, and report information that is accessible for each office location. The instances of data in the search results for the Loans data object 404 comprise specific loans (identified by loan number) for ABCD Company office locations along with other information, including loan origination date, remaining principal and report information that is accessible for each loan. The Purchase Orders data object lists information associated with purchase orders associated with ABCD Company. Each of the data objects includes instances of data which include hyperlinks to other related instances of data, where the instances of data are related by primary and/or foreign keys.

For example, FIG. 5 depicts a graphical user interface of the Customers data object for the search results for ABCD in the enterprise, further allowing the user to navigate to the Loans data object or the Purchase Order data object (via boxes 502). The display in FIG. 5 further shows the number of search results for ABCD associated with each data object (e.g., 32 ABCD company locations for the Customer data object, 22 loans associated with ABCD Company for the Loan data object, and 22 purchase orders associated with ABCD Company for the Purchase Order data object as shown in the boxes 502). As with the previous example, the graphical user interface of FIG. 5 also provides the feature of displaying the search results on multiple pages, with the option of navigating to a specific page of search results (as shown in the box 504). In addition, the displayed information can organize the search results based upon city and state, where hyperlinks can be navigated so as to easily find information about ABCD Company in a specific city or state (see hyperlinks located at reference number 506). Information about the Account Manager, profitability and risk analysis reports are also accessible via hyperlinks for each ABCD Company location listed in the search results. When a hyperlink is navigated by the user for a particular instance of data, information that is linked with that instance of data by report parameters is presented in accordance with a predefined information format.

The graphical user interface can also present data from the search results as shown in FIG. 6, in response to a user navigating by hyperlink a particular instance of data within the Company column of the search results for the Customers data object 402 depicted in FIG. 4. The displayed information comprises a table 602 with information for the ABCD Company location that is similar to that shown in the Customers data object 402 but also with further information including data instances with further hyperlinks to related data instances (where the data instances are linked by primary/foreign keys of the data objects). One hyperlink is shown for the Related Lists column as table 604, in which information about orders associated with the ABCD Company location listed in table 602 is displayed, including further hyperlinks to instances of data associated with some of the displayed instances of data.

An example of navigating an instance of data in the Reports column for Customers data object 402 is depicted in FIG. 7. In particular, navigation of the EOQ Loan instance of data provides a link to a table 702 of End of Quarter Outstanding Loans for this particular ABCD Company location, where the report is provided by a reporting system having information about each company (or a selected number of companies) for the Customers data object.

The data object search system further allows a user to design or customize the types of data for display. In particular, the configuration settings for a particular data object can be established based upon an attribute table such as is shown in FIG. 8. This table, which can be stored in the repository 120 (or any other suitable location of the data object search system) provides information regarding columns of data tables that define the data object and that can be searched and displayed (e.g., in a summary display or a full display) and also showing relationships with other, related data objects. The attributes for the Customer data object are shown in FIG. 8, in which a Customers table and a Contacts table (which can be from one or more data sources from one or more data management systems) are combined, include information regarding which attributes are displayed in both a summary object display (under the “Summary” column) or a full object display (under the “Display” column), where “Y” indicates yes and “N” indicates no. This table further indicates which attributes are searchable (under the “Searchable” column), as well as whether there are any relational data objects for a particular attribute (under the “Rel Object” column) as well as the relational type (under the “RelType” column). For example, the CustName attribute in the Customers table (which is displayed as “Company”) is searchable by the data object searcher of the data object search system and is displayed in both a summary object display as well as a full object display. FIG. 9 shows the data that is displayed for a search query for information relating to ABCD Company in both the Summary Object form (table 902) and the Full Object form (table 904) based upon the attribute information shown for the Customer data object in the table of FIG. 8.

The SalespersonID attribute (displayed as “Account Manager”) has a reference to a related object (SalesPerson), such that the instance of data in the displayed Account Manager column includes a hyperlink (via primary/foreign keys associated with each data object) to a related instance of data that provides information about that Account Manager. An attribute table for the SalesPerson data object can also be provided, with similar configuration settings to facilitate searching and/or display of certain attributes as well as providing information showing relationships between related objects (which can be linked by primary/foreign keys for the related data objects). In addition, the Orders attribute is related to the Customers table as a list type relationship and provides a hyperlink (via primary/foreign keys associated with each data object) to the Orders data object so as to provide a list of orders corresponding to the associated Company.

The attribute table shown in FIG. 8 could be predefined and set prior to searching by a user. Alternatively, the data object search system can be configured to permit an attribute table to be manipulated by a user, for example, by allowing the user to change settings such as which attributes would be displayed and/or which would be searchable. In response to a search query, the data object searcher searches all (or a selected number of) tables and selected attributes (could be some or all for each table) of a particular data object based upon the configuration settings set forth in the attribute table for this data object. Optionally, the configuration settings can be selectively adjusted to control which tables and/or which attributes of a data object are searched by the data object search system.

Thus, the present invention facilitates the linking of data relationships in search results of data management systems including structured data, such as relational database management systems, by hyperlinks so as to permit easy navigation by a user from one instance of data to another, related instance of data. The data object search system further facilitates control of how the data objects are searched (by setting and/or selectively adjusting attributes and/or tables to be searched in the data objects) and/or how search results are displayed (by setting and/or selectively adjusting which attributes from which tables are to be displayed for certain display settings).
